Building a website without the website architecture is like building a house without a blueprint. We need to write on paper your ideas with our knowledge and suggestions before we start coding. We'll then code as planned. Otherwise imagine how difficult it might be for an architect to add or remove columns to a house and how expensive it might also be for you to pay for materials and resources each time the architect add or remove a new column. When we keep things organized it helps the process to get it complete quickly.
